Question

Which numbers should be multiplied to obtain 1832 - 1392?

44 and 44

1936 and 1936

44 and 322

33350 and 33628

Answer 1

183^2 - 139^2 = 14168

so ans is 44 and 322 as 44*322 = 14168

Answer 2

Answer: The correct option is (C) 44 and 322.

Step-by-step explanation: We are given to select the correct pairs of numbers that should be multiplied to obtain the following numerical expression :

`E=183^2-139^2~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

We will be using the following algebraic formula to solve the given problem :

`a^2-b^2=(a-b)(a+b).`

From equation (i), we have

`E\\\\=183^2-139^2\\\\=(183-139)(183+139)\\\\=44* 322.`

Thus, we should multiply 44 and 322 to get our result.

Option (C) is CORRECT.
